In 2125, mankind entered the "Transparency Era". With the popularization of brain-computer interface technology "oracle system", thinking is no longer private. But all this meant nothing to Lin Che - he was born with an "auditory center symbiont abnormality", a rare mutation that was misdiagnosed as a mental illness, which allowed him to passively hear the superficial thoughts of everyone around him since birth, as if he was in a hell of noise that never goes silent all day long.
For twenty-eight years, Lin Che has relied on a dual identity to survive: during the day, she is the most patient caregiver at an autism rehabilitation center, and at night, she is the most sought-after "memory cleaner" on the black market, using her twisted abilities to help clients erase painful memories. He believed that he was an accident of evolution and a monster of civilization, until that rainy night, a dying client transmitted the last picture to his mind before his thoughts dissipated:
A huge white tower, with a pulsating "cocoon of collective consciousness" suspended on the top of the tower - and the thinking noise of seven billion people around the world is being quietly extracted and integrated into it through the daily ports of the "oracle system".
